Which of the following actions is NOT allowed for student pilots?

Carrying non-revenue passengers is prohibited for student pilots as it compromises safety and accountability during training. The primary purpose of a student pilot's flight is to gain experience and skills under the supervision of a certified flight instructor. Allowing non-revenue passengers could distract the student pilot and potentially introduce additional risk into the flight environment, especially since they are still in the learning phase and may not yet be proficient in handling all types of in-flight situations or emergencies.

In contrast, student pilots can conduct solo flights after obtaining the required endorsements from their instructors. They can also pursue flight instructor endorsements, which are essential for advancing their training and experience. Flying in controlled airspace is permitted as long as the student pilot has received proper training and endorsements to do so, ensuring they are adequately prepared for the complexities of operating in such environments. This ensures that the training remains focused on developing the skills essential for ensuring safety in aviation operations.
